What are FRP Fans?

FRP is the acronym for “Fiberglass Reinforced Plastic” so in the case of FRP fans, these units are designed for corrosive air movement applications. Depending on the model, the construction might include a backward curved wheel and have a controlled construction of lamination. With this, the fan would comply with current industry specifications. Typically to create a spark-resistant product, more layers of graphite impregnation and corrosion resistant cloth are added.

Markets for FRP Fans

There are different markets that use FRP fans, one being semiconductor manufacturing. For this industry, different corrosive and toxic materials are used during fabrication. In addition, prior to chips being assembled, different acids are used to clean the metals and throughout various stages of manufacturing, corrosive gases and acids are needed, the most common being phosphoric acid, ammonia, hydrofluoric acid, and hydrochloric acid.

For semiconductor manufacturing and most other industries, to be efficient and achieve success, it is vital that all systems run continually. However in doing so, workers could be at risk. In this situation, the facility where manufacturing occurs must have proper ventilation. Without proper venting, workers are exposed to acids and chemicals that could pose a significant health risk.

The great thing about FRP fans is that they offer the level of ventilation needed for semiconductor manufacturing and other industries, as well as applications. In addition, these fans have a solid reputation for providing years of service without fail and with very little maintenance needed. Because of this, people can work in a safe environment and there is little operation downtime. For more detail click here...

A Review of Variable Frequency Drives

Variable frequency drives (VFD), which are also known as AC drives, frequency drives, inverters, speed drives, and micro-drives, are motor controllers capable of driving electric motors. The way this is accomplished is that the frequencies and voltages going to electric motors are varied.

Brief Introduction to Variable Frequency Drives


This type of adjustable speed drive is used primarily in electro-mechanical drive systems as a means of controlling torque but also AC motor speed by varying input voltage and frequency of the motor. There are several applications that use these drives to include smaller appliances to massive mine mill compressors.

Today, roughly 25% of electrical energy in the world is consumed by electric motors within various industrial applications. Using a variable frequency drive in centrifugal load service, motors save energy. Although these drives are extremely popular within North America, they hold a very small market in other parts of the world. The bottom line, installation of variable frequency drives could significantly improve energy efficiency.

Throughout the past four years, the cost and size of variable frequency drives has been dramatically reduced thanks to power electronics technology. In addition, overall performance has been improved upon through advances made in semiconductor switching devices, control and simulation techniques, control software and hardware, and different drive topologies.
